Patented Apr. 23 1313 application filed July 8, 1918. Serial Iil'o. 233,993.

To all whom it may concern Be it known that I, JOHN P. How, a subect of the Emperor of Austria, residing at "Watertown, in the county of Middlesex and State of Massachusetts, have invented new and useful'l-mprovements in Electric Fans and Casings, of which the; following is a specification.

This invention relates to a useful and ornamental device particularly adapted to be used in limousine automobiles, the object of the invention being to provide aconvenient means for cooling the interior of a limousine body.

The device is so constructed that when a switch is operated to'start the rotation of a fan a pair of doors will be automatically opened in order that the air from the fan may be directed without obstruction into the interior of the car body' and when the circuit is broken the fan will stop rotating and the doors will be automatically closed so as to present a neat and ornamental appearance.

The invention consists in the combination and arrangement of parts set forth in the and articularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved electric fan and casing with the doors of the casing closed.

Fig. 2 is a sectional elevation taken on line a 2 of Fig. 1.

Fig. 3 is a sectional underneath plan taken on line 33 of Fig. 1, partly in section, of v the mechanism for operating the switch and doors with the cap which incloses the said mechanism removed and the doors open.

- Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 5 is the casing, provided with a chamber 6 in which is located a rotary fan 7 which is fast to the shaft 8 of an electric motor 9. The electric motor is driven by batteries connected thereto by wires 10 and 11 which are connected to contact plugs 12 and 13, respectively. The contact plugs I 12 and 13 are located in a block 14 of insulating material which is clamped to the bottom of the casing by a bracket 15.

A switch pin 16 1s slidably mounted n a bracket 17 fast to the casing and pro]ects through one side of the bracket and through the insulating block 1 1 and contact plugs 12 and 13 when the electric circuit 15 closed. Said switch pin is provided with a head 18 and a spring 19 encircles said switch pin bearing at one end against the bracket 17 and at the other end against the head 18 of said pin. lin Fig. 3 the switch pin is shown as projecting through both of the contact plugs 12 and 13, thus closing the electric circuit so that the'fan will be at that time rotated by the motor.

A pair of doors 20 and 21 are fastenedto shafts 22 and 23 rotatably mounted on the casing 5. These doors serve to open and close the chamber 6.. 0n the lower ends of the shafts 22 and 23 are fastened pinions 2i and 25 which engage rack bars 26 and 27 respectively. The rack bar26 is guided in brackets 28, 29and 30 and the rack bar 27 is guided in brackets 31, 17 and 30. These rack bars engage a pinion 32 on opposite sides thereof. I

The pinion 32 is fast to a vertical stud 33 move the same toward the left to close the circuit.

The general operation of the device hereinbefore specifically described is as follows: Assuming the parts to be in the relatlve positions shown in the drawings, Fig. 3, it will be noted that the switch pm 16 ism position to close the electric circuit by oinmg the contact plugs 12 and 13 together and the electric fan 7 is then being rotated by the motor 9, and at this time the doors are If it is desired to sto the fan and close the doors, this may be one simultaneously by giving the stud 33 a quarter rotationby means of the crank handle 34,-thus rotating the pinion 32 and moving the rack .27 toward the left and the rack 26 toward the right (Fig. 3). As said racks move away from each other, the pinions 24 and 25 are till rotated in the proper direction to close the doors and simultaneously the rack 26 moving toward the right allows the spring 19 to move the switch pin 16 toward the right and 1 casing is also provided with perforations or slits 37 so that the air has free circulation from the interiorof the casing to the interior of the automobile body. In addition the casing is provided with a notepad 38 and a mirror 39 which slide vertically into the back part of the casing. As a further means of rendering the device useful as well as ornamental a counter 40 is provided for the months and days of the-month and another counter 41 for the years. A watch 42 is also mounted upon the central portion of the casing above the doors, the whole device thus belng made very useful and ornamental.
